Tov all @hom t may concern:v

' Be it known that we, SAMUEL D. IRWIN and STEPHEN E. JOHNSON, Jr.,citizens of the United States, residing,

respectively, at Floydada and Spur, in the counties of Floyd and Dickensand State of Texas, have invented certain new and useful Improve-V mentsin Cotton-Bur Separatore; and we doD 'hereby declare the following tovbe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appert-ains to make and e,use thel saine, reference being had to the accompanying drawings, and tothe letters and figures of reference marked thereon, which forma part ofthis specification.

" This' invention relates to new and useful improvements in apparatusfor'separating.

j 'A'frost bitten cotton bur usually opens but a slightdistance, butcontains a considerable amount :of lint, therefore making vitnecessary-'to break openthe `burandseparate the lintfrom the bur andsha'le'b'efore'the gin "cansuccessfully handlethe product. Cotton in buris 4frequently gathered lwhiledew is upon fthem and hence have novchance to dryout' and ifattempted to, ginin this condition, the moistlint with'.V the addition of vegetable gumfup'n -th'ebur twines aboutthe cross wire in the screen of the usual gin machinery and cutting offthe screensurface causing the same to chokerupf By the provision nof thefeatures of the present invention thesel 'features are A',elimi natedand a machine is afforded having varous details of construction,combinations and arrangements of parts which will be hereinafter fullydescribed, shown in the accompanying drawings and then specificallydefined in the appended clalms.

Our invention is illustrated in the accompanying drawings, which withthe letters of reference marked thereon form a part of)V *has beltedconnections 13.

p and inthe trough 21 Fig. 5'is a sectional view von line 5 5 of Fig. 4looking lin the direction ofthe arrow.' Reference now being had to thedetailsr of the drawingsbynumerals:

l designates az casingin the walls of which are mounted theshafts 2,carrying the drums 3 overvwhich `the endless conveyer 4 passes havingteeth 5 thereon for the purpose of engaging the lint as it comes incontact with the belt. A feed pipe 6 leads intosaidcasf ingV and intowhich'thecotton as it is un# loaded `is blown into the separator. Aseries of inclined blades 7V are disposed lat lan in. clination in thecasingover the endless conveyer as shown in Fig. l of the drawings, andagainst whichthe cotton isblown, being deflected downwardy against thebelt.

. Other blades 8, arranged at inclinations to one another and spacedapart a slight distance, `are mounted lwithinV the casing and spacedapart from the conveyer, asuitable space 9 .intervening'between theouter portions of the blades 8 and the wall 10 of the casing, saidspace9 being adapted to receive such foreign matter -as broken burs which maypass through the spaces between Vthe blades 8. -A conveyer 11 is mountedat the lower end of .the casing .and is adapted to carry away :suchforeign matter as. may fall to thev bottoml Offthe casing. Said endlessconveyer 4 is driven by power applied to the pulley lxed. tothe shaft 2carryingthe lower'drurniand upon which shaft the pulleys 14 and 15 aremounted. 'A pulley 11 is xed to theshaft of the conveyer l1 and with apulley 2 upon the'shaft E?.

By referring to they detailed views of the drawings, it will be notedthat the series of Aug. 20, 191s.V y Appueauonpieanayao,191s. serilNo.235,535.1

blades -8 are mounted in cleats 16 spaced apart and the inner end ofeach blade is rounded as at 16.

A suitable space 17 interven'es between i i the endless lbelt 4 and theinner ends of the series of blades 8 and in which the larger portions ofthe burs which do not pass be tween the blades 8 and which are thrownagainst the blades 8 by centrifugal force, are adapted to fall `into ascrew conveyer 18 having a shaft 18 upon which adriving pulley 19 isfixed, adapted'to have belted connection with the pulley'l. A brush 20is mounted in suitable bearings in the casing which communicates casinglows The cotton is unloaded from the wagon` through a suitable burbreaker and blown into the pipek 6 and against the blades 7 which aredisposed at an inclination to one another across i the feed pipe andwhich bladeswill obstruct the passage of the current of. air, the.blades thus. causing-,the coti ton and burs to bethrown againsttheteeth upon the endless conveyer belt.'` The teeth upon fthe endlessconveyer belt will carry the cotton. against the. inner endsoi theblades 8 andthe burbeing heavier than the lint .will be thrown by4centrifugal" force against the blades Sand tend to yseparate the linttherefrom,- portions of the bursapass-` ing through the blades 8 andinto thespace 9.,l Theparticles ofbursand other foreign1natter.,e1itering i the space9 will fall: by gravity4 yinto theconveyeroll and bei conveyed away. Larger particles of burs `which donot pass through the bladesy Sfiwill *..all into thespacel' into the'.`conveyer .718.. rlhe lint which adheresto .the teeth ofthe belt will beseparatedtherefroin bythebrush 2O and drawn to the gin through the.passageway in which Ethebrush is located. ,r
